美国企业现行股票期权计划存在的问题与争论

90年代以后,由于美国的股票市场、税收政策以及会计准则等都有力地促进了股票期权计划的发展,使股票期权在激励经理人员以及协调经营者与股东之间的利益关系等方面都发挥了良好的作用。但是,这一计划的实施并不完美,在实践中也暴露出许多不可忽视的问题,如经理人员的报酬与公司业绩脱节、激励作用弱化、股东利益受到损害等等,这些问题在西方引起广泛的关注与争论,同时对我国的公司治理也有一定借鉴与启示。

Comparing Decision Rules that Incorporate Customer Diversion in Perishable Asset Revenue Management Situations

Most of the initial work on perishable asset revenue management (PARM) situations assumed no possibility of customer diversion from one product class to another when the former is made unavailable. In this paper, an evaluation is made of the few published decision rules that incorporate the realistic and common behavior of customer diversion (or sell-up). We present a new heuristic approach that incorporates diversion and could be used by airlines and other relevant industries to achieve improvements in expected contribution of 0.25 to 2.5% over the approach currently used. The sensitivity of the difference in expected contribution between these rules is tested relative to changes in the input parameters, and managerial insights are presented.     

公司治理、审计风险与审计定价——基于CCGINK的经验证据

本文采用南开大学公司治理研究中心发表在2004年<管理世界>第二期的论文中公布的2002年度"中国上市公司治理100佳"的公司治理指数作为公司治理质量的替代变量,以"100佳"中的55家2001年至2004年的数据作为研究对象,采用多元回归方法,分析公司治理指数、审计风险、审计师规模与审计定价的关系.结果发现,公司治理指数越高,审计定价越低;随着公司治理指数提高.国际四大和本土五大明显降低了审计定价,而本土次五大的审计定价却没有明显下降,说明审计定价受到公司治理风险影响,国际四大及本土五大对源于公司内部治理的风险更加敏感.原因可能是大型事务所运用了风险导向审计模式,在争取到优质客户后,采取了合理的风险定价策略,以保持优质客户.上述发现对大型审计师获得审计收费声誉溢价的观点做了局部修正.     

Coordinating pricing and production decisions for multiple products

We consider a dynamic problem of joint pricing and production decisions for a profit-maximizing firm that produces multiple products. We model the problem as a mixed integer nonlinear program, incorporating capacity constraints, setup costs, and dynamic demand. We assume demand functions to be convex, continuous, differentiable, and strictly decreasing in price. We present a solution approach which is more general than previous approaches that require the assumption of a specific demand function. Using real-world data from a manufacturer, we study problem instances for different demand scenarios and capacities and solve for optimal prices and production plans. We present analytical results that provide managerial insights on how the optimal prices change for different production plans and capacities. We extend some of the earlier works that consider single product problems to the case of multiple products and time variant production capacities. We also benchmark performance of proposed algorithm with a commercial solver and show that it outperforms the solver both in terms of solution quality and computational times.     

An algorithm to determine the parameters of SU -curves in the johnson system of probabillity distributions by moment matching ∗

We describe an algorithm to fit an S_U -Curve of the Johnson system by moment matching. The algorithm follows from a new parametrization, and reduces the problem to a root finding procedure that can be implemented efficiently using a bisection or a Newton-Raphson method. This allows the four parameters of the Johnson curve to be determined to any desired degree of accuracy, and is fast enough to be implemented in a real-time setting. A practical application of the method lies in the fact that many firms use the Johnson system to manage financial risk     

The Impact of Revenue‐Maximizing Priority Pricing on Customer Delay Costs

Speed is an increasingly important determinant of which suppliers will be given customers' business and is defined as the time between when an order is placed by the customer and when the product is delivered, or as the amount of time customers must wait before they receive their desired service. In either case, the speed a customer experiences can be enhanced by giving priority to that particular customer. Such a prioritization scheme will necessarily reduce the speed experienced by lower‐priority customers, but this can lead to a better outcome when different customers place different values on speed. We model a single resource (e.g., a manufacturer) that processes jobs from customers who have heterogeneous waiting costs. We analyze the price that maximizes priority revenue for the resource owner (i.e., supplier, manufacturer) under different assumptions regarding customer behavior. We discover that a revenue‐maximizing supplier facing self‐interested customers (i.e., those that independently minimize their own expected costs) charges a price that also minimizes the expected total delay costs across all customers and that this outcome does not result when customers coordinate to submit priority orders at a level that seeks to minimize their aggregate costs of priority fees and delays. Thus, the customers are better off collectively (as is the supplier) when the supplier and customers act independently in their own best interests. Finally, as the number of priority classes increases, both the priority revenues and the overall customer delay costs improve, but at a decreasing rate.     

Capacity Investment Under Responsive Pricing: Implications of Market Entry Choice*

We consider a manufacturer’s new market entry problem when it already has some established facility in its existing market. We consider two common market entry strategies: the export strategy and the foreign direct investment (FDI) strategy. In the export strategy the firm increases the capacity at its existing facility and subsequently allocates the output to the existing and the new market dynamically, depending on realized market conditions. The export strategy is a flexible strategy. In the FDI strategy, the firm invests in a dedicated capacity to serve the new market only. The FDI strategy is a (partially) dedicated strategy. We study these two strategies from a planning perspective, that is, how the firm’s strategy choice influences the optimal capacity levels. We find that the firm’s strategy choice can significantly impact the optimal capacity investment levels. We prove, for example, that the firm may enter the new market in the export strategy but not in the FDI strategy, even if the capacity investment cost is identical in the existing and the new market. In addition, we prove that the firm may invest a strictly higher capacity level in the export strategy than that in the FDI strategy. We also prove that new market entry in the FDI strategy may strictly decrease the firm’s supply to its existing market but this is not so in the export strategy, and hence policy makers should carefully consider the implications of trade regulations on firms’ market entry choices.     

Reducing Packaging Waste and Cost via Consumer Price Discounts

Low‐waste packaging may imply an inconvenience to consumers and cause firms to offer a compensating price discount. For example, Starbucks’ “Take the Mug Pledge” campaign provides a 10‐cent discount for customers who purchase coffee without a standard cup (i.e., customers provide their own cup). Understanding how such a discount drives demand and profit is the focus of this article. We consider a monopolist that can offer a reduced‐packaging option for its product at a variable cost savings. That option implies a transactional “inconvenience” cost for consumers. While that transactional cost is generally positive, our model also permits some consumers to associate convenience with reduced packaging. We derive the optimal price and discount that maximize profits. We show the optimal discount is bounded by the magnitude of the variable cost savings associated with the packaging reduction. We explore when the optimal discount is negative (a price premium), which requires a specific proportion of consumers to associate convenience with reduced packaging. We also derive conditions under which the firm should price to eliminate demand for the standard product, rather than segment the market, to leverage the variable cost savings of reduced packaging. When the variable cost savings are low (e.g., as is true for Starbucks), we show the profit curve for the segmenting policy is relatively flat for a discount up to several multiples of the cost differential. Finally, we demonstrate the potential for the reduced packaging option, with optimal discounting, to simultaneously increase profit and consumer surplus while reducing waste.
